NAME

6       hpsa - HP Smart Array SCSI driver
7

SYNOPSIS

9       modprobe hpsa [ hpsa_allow_any=1 ]
10

DESCRIPTION

12       hpsa is a SCSI driver for HP Smart Array RAID controllers.
13
14   Options
15       hpsa_allow_any=1:  This  option allows the driver to attempt to operate
16       on any HP Smart Array hardware RAID controller, even if it is  not  ex‐
17       plicitly  known to the driver.  This allows newer hardware to work with
18       older drivers.  Typically this is used to allow installation of operat‐
19       ing systems from media that predates the RAID controller, though it may
20       also be used to enable hpsa to drive older controllers that would  nor‐
21       mally  be  handled by the cciss(4) driver.  These older boards have not
22       been tested and are not supported with hpsa, and cciss(4) should  still
23       be used for these.
24
25   Supported hardware
26       The hpsa driver supports the following Smart Array boards:
27
28           Smart Array P700M

61   Configuration details
62       To configure HP Smart Array controllers, use the HP Array Configuration
63       Utility (either hpacuxe(8) or hpacucli(8))  or  the  Offline  ROM-based
64       Configuration  Utility  (ORCA) run from the Smart Array's option ROM at
65       boot time.

FILES

68   Device nodes
69       Logical drives are accessed via the  SCSI  disk  driver  (sd(4)),  tape
70       drives  via  the  SCSI tape driver (st(4)), and the RAID controller via
71       the SCSI generic driver (sg(4)),  with  device  nodes  named  /dev/sd*,
72       /dev/st*, and /dev/sg*, respectively.
73
74   HPSA-specific host attribute files in /sys
75       /sys/class/scsi_host/host*/rescan
76              This  is a write-only attribute.  Writing to this attribute will
77              cause the driver to scan for new, changed,  or  removed  devices
78              (e.g.,  hot-plugged  tape drives, or newly configured or deleted
79              logical drives, etc.)  and  notify  the  SCSI  midlayer  of  any
80              changes  detected.  Normally a rescan is triggered automatically
81              by HP's Array Configuration Utility (either the GUI or the  com‐
82              mand-line  variety);  thus,  for logical drive changes, the user
83              should not normally have to use this attribute.  This  attribute
84              may be useful when hot plugging devices like tape drives, or en‐
85              tire storage boxes containing preconfigured logical drives.
86
87       /sys/class/scsi_host/host*/firmware_revision
88              This attribute contains the firmware version of the Smart Array.
89
90              For example:
91
92                  # cd /sys/class/scsi_host/host4
93                  # cat firmware_revision
94                  7.14
95
96   HPSA-specific disk attribute files in /sys
97       /sys/class/scsi_disk/c:b:t:l/device/unique_id
98              This attribute contains a 32 hex-digit unique ID for each  logi‐
99              cal drive.
100
101              For example:
102
103                  # cd /sys/class/scsi_disk/4:0:0:0/device
104                  # cat unique_id
105                  600508B1001044395355323037570F77
106
107       /sys/class/scsi_disk/c:b:t:l/device/raid_level
108              This attribute contains the RAID level of each logical drive.
109
110              For example:
111
112                  # cd /sys/class/scsi_disk/4:0:0:0/device
113                  # cat raid_level
114                  RAID 0
115
116       /sys/class/scsi_disk/c:b:t:l/device/lunid
117              This  attribute  contains  the  16  hex-digit (8 byte) LUN ID by
118              which a logical drive  or  physical  device  can  be  addressed.
119              c:b:t:l are the controller, bus, target, and lun of the device.
120
121       For example:
122
123                  # cd /sys/class/scsi_disk/4:0:0:0/device
124                  # cat lunid
125                  0x0000004000000000
126
127   Supported ioctl() operations
128       For  compatibility  with  applications written for the cciss(4) driver,
129       many, but not all of the ioctls supported by the  cciss(4)  driver  are
130       also  supported  by the hpsa driver.  The data structures used by these
131       ioctls  are  described  in   the   Linux   kernel   source   file   in‐
132       clude/linux/cciss_ioctl.h.
133
134       CCISS_DEREGDISK, CCISS_REGNEWDISK, CCISS_REGNEWD
135              These  three  ioctls  all do exactly the same thing, which is to
136              cause the driver to rescan for new devices.  This  does  exactly
137              the same thing as writing to the hpsa-specific host "rescan" at‐
138              tribute.
139
140       CCISS_GETPCIINFO
141              Returns PCI domain, bus, device, and  function  and  "board  ID"
142              (PCI subsystem ID).
143
144       CCISS_GETDRIVVER
145              Returns driver version in three bytes encoded as:
146
147                  (major_version << 16) | (minor_version << 8) |
148                      (subminor_version)
149
150       CCISS_PASSTHRU, CCISS_BIG_PASSTHRU
151              Allows  "BMIC"  and  "CISS" commands to be passed through to the
152              Smart Array.  These are used extensively by the HP Array Config‐
153              uration   Utility,   SNMP   storage  agents,  and  so  on.   See
154              cciss_vol_status at ⟨http://cciss.sf.net⟩ for some examples.
